Lighting should not cause insects and other animals to lose orientation or interfere with their ability to find food. Without insects, our lovely trees and flower beds would no longer be pollinated.
What can you do to make your garden insect and animal-friendly and still have beautiful lighting? One solution lies in choosing the right light colour.
1. Which light colour is insect-friendly?
Insects are attracted to light with a high blue ratio. They basically confuse that light with the light of the moon, which they rely on for orientation. We call that ‘cold light’. Neutral white light ranges between 3,300 and 5,300 Kelvin, while daylight white light is above 5,300 Kelvin. The colder the light, the more attractive a luminaire becomes for insects. They fly aimlessly around the luminaire, become disoriented and are no longer able to forage for food.
2. What about directing the light?
We like to highlight the things that fill us with pride in our gardens: perfectly pruned shrubbery, majestic trees, our most prized flowerbeds. It is, however, important to direct the light correctly to ensure we protect our garden’s fauna.
3. How do I use lighting responsibly?
Many animals and insects are nocturnal, meaning they move under the cover of darkness. When we illuminate our gardens until late at night, we make it impossible for these creatures to search for food, which impacts their natural life. That is why it is important to only light up areas we are actually using: You don’t need light in the front garden, while you are having a barbecue on the patio.
Some areas will always need light for orientation, while others only need ambient lighting from time to time. When you do need light in such areas, be sure to think about surfaces that do not reflect light unnecessarily. Dimmable luminaires are great for adjusting brightness and create a wonderful ambiance, while reducing the impact on animal life. Have a look at our Light Lexicon for more information about dimming.
